Amsoil Vs. Redline: A Handy Comparison Guide

Cars are the second most expensive investment most of us will ever make in our life. They will be fulfilling our transportation needs for a considerable number of years. While they might be built to last you for decades, in order to guarantee they offer you OPTIMAL performance – you need to have them maintained and repaired regularly to ensure smooth running. Therefore, it is vital that you never delay in getting an oil change, as your parts require good lubrication for efficient working.

However, don’t just go for any oil you find on the shelf of an automotive store. Getting an oil change USED to be a simple thing, but ever since the inception of different “types” of cars and engines – the same oil doesn’t work for every vehicle anymore. You’ll find auto shops stocked with variants of synthetic and regular oil from multiple brands like Amsoil and Redline, and you are likely to hear conflicting recommendations about which is best. This article rids the confusion by giving a detailed review of both: Amsoil and Redline.

  1. Another Amsoil commercial from with in …..i have used both in HD motorcycles and Redline is the best by far……………..

  2. I have used Amsoil for over a decade and drove one vehicle to 535,000km (300,000 miles) on it. It wasn’t burning or using any oil either. There is also a video floating around YouTube about a guy that drove his van 1,000,000 miles on Amsoil. It was independently verified to be true as well. There are a lot of great oils out there that will yield good results but for me Amsoil is the best. Happy Motoring.

  3. I am an Amsoil user and Dealer also. I contacted Shell Oil company before I started this business and asked the answer man there what he thought of Amsoil products. The answer man said that, Amsoil is far superior to anything on the market today, including anything we put out.

    That is a direct quote from there tech man about Amsoil and his thoughts. This is a man with many years of knowledge in the technical field today.

    I will continue to use Amsoil in all my cars and trucks and my customers equipment. It may cost me a little more to use it in a customers equipment, but it is well worth it in the results in the long run.
